Wanted Lawn-Boy/Trade 196cc Clone

[Russ2251]

Will trade 196cc 6.5hp Honda GX-200 clone (Lifan) for Lawn-Boy DuraForce engine.
Clone is brand new and was only run once for QC evaluation and has no issues. I have no need for this engine and has to go.

Lawn-Boy (engine only) can be any year DuraForce model 'E'. Must be a running engine but will consider non running if in good/excellent mechanical condition (unintended oxymoron). Contact me through diygokarts.com.

Oh,oohh!.... Russ is making his move! I saw a type "g" on ebay last night, but it looked like the 4.5hp model. That's why I didn't bug you with it, plus I've got the feeling that if it's DuraForce, you've seen it before I have! Good luck!

http://louisville.craigslist.org/grd/672676135.html

[Russ2251]

Yup...model 'F' 4.5 hp. First engine I used for kart. I have since acquired 3 others including electric start.

[ironman]

cool than im going to go buy it 25 thats not bad for that right russ

[Russ2251]

Depends, not all models will work. Model #'s are not posted so I can't cross reference part #'s for usable crankshafts.
BBC and geared auxiliary pto engines won't work.
I never tried to fit electric start (too heavy).
Some electric start models do not have a recoil which comes in handy if starter fails.
I would not purchase these 'oldies' as mechanical condition is unknown. Would be better off cruising neighborhood or scrapyard for freebies. They're out there, you just have to look.

[ironman]

well russ i went out and bought all 5 of them for 50 buck 10 dollars each he said they did run but you know how that goes i need help to identifie them here we go.

[Russ2251]

5024 is 1977 model 'D 433' engine and there is no easy way (that I know of) of setting up exhaust pipe/muffler. You will see what I mean when disassembled.
Same thing for 7261 (1972) and 7263 (1974). Both of these are 'D 600' engines.
All the above are 3.5 hp.
Unidentified mowers are 'F' engines and can possibly be used. PTO's have to be examined which would require removing engines from mower housing. These are 4.5 hp.

[ironman]

you are the man russ.:thumbsup: so would say than its a go for these im going to start tomorrow taking all of these motors apart from the decks any thing i need to look out for.are these 5/8 shaft inputs on the first 3

[Russ2251]

7/8" shafts on first 3. Unidentified will have to measured, and if usable will be also be 7/8".

[ironman]

wow i didn't realize that big thought it would be a 5/8 hum...or even a 3/4

[Russ2251]

DuraForce and Briggs 2 cycle are just under 1".

[ironman]

so where did you find a clutch at to fit yours its a 7/8 too right
russ check out these old schools on ebay right now. 270245356591

[ironman]

just looking out for you:2guns:

[ironman]

ok well i figure if im going to be using these motors be a good idea to get the manual on them .so printing up the book on all of them now. thanks for the info russ on another thread i seen where you said to go to to get the manuals.

[Russ2251]

on another thread i seen where you said to go to to get the manuals.Best advice I can give.
Never EVER make assumptions when tearing engines down or re-assembling. Torque all screws/bolts according to specs. When you run across needle bearings be careful not to drop them as they are notorious for getting lost. If you do drop them, don't use a magnet to pick them up. Reasons are obvious.

o my:censored: there is no way to put a exhuast on these motors this is a problem for sure because man its going to be very loud.started on one of the motors today got it off the mower and setting it up on a stand will post picture later got a few ? already:mad2: :mad2:

[Russ2251]

there is no way to put a exhuast on these motors this is a problem for sure because man its going to be very loud.I did mount and run the 'D' engine (5024, 7261, 7263) but never used it because of exhaust problem.
Check out the unidentified engines first as these appear to be the most promising because they have threaded exhaust holes.
I will post pics of usable engine blocks this evening. Usable engines are model 'F's', 'V's' and 'E's'.
Your 2 unidentified engines are 'F' engines and show the most promise.
Hopefully they do not have auxiliary pto for transmission.

[ironman]

man i hope so im going to take all motors off tonight to find out i would really like to make it work. i plan on doing a dual 2 cycle setup is the plan.ill find out what they look like tonight.

Hello,
I was diverted here from a lawnmower site after seeing russ's kart. I was wondering if you tore that commercial lawn boy apart? It would be a pain to use that motor potentially due to the clutch setup, I would think. Any chance you would sell the motor & handle to me? I'm in Wi so you'd have to ship. I could swap you a duraforce motor as well. They are everywhere around these parts. I also have numerous f engines as well. Let me know. Sorry to intrude like this on my first post. Thanks. -Dave

[ironman]

well send a picture sounds good so tell me what kind of trade you wanting to make im open to motors cash what ever just let me know.

[Kenny_McCormic]

Why cant an exhaust be mounted? I want pics, maybe my afro engineering skills will go to work.

[kibble]

Why cant an exhaust be mounted? I want pics, maybe my afro engineering skills will go to work.

That's what I want to know. The only reason I can think of that you couldn't mount an exhaust pipe to it easily would be that there is nowhere to screw a flange or it's just a hole that can't be threaded. :confused:

[Russ2251]

there is nowhere to screw a flange or it's just a hole that can't be threaded.Yes to both.
Engine muffler is mounted to underside of mower housing.
When engine is bolted to mower housing, it meets muffler flange with a gasket sandwiched in between.
First pic is of exhaust port.
Second pic is completed prototype with 'D' engine. This was never tested. A couple of weeks later I came across an 'F' engine (freebie) which is more user friendly.
Pics were taken 2 years ago.

[Russ2251]

I think we have an LB collector in our midst.

"I see!" Said the blind man as he picked up his hammer and saw.

[Russ2251]

Some guy just offered me $1200 for my kart. That would be about a $400 profit.
I'm considering it. What a country!!!

[kibble]

HOLY CRAP! Are you willing to let go of your 2 cycle baby though?

[Russ2251]

Are you willing to let go of your 2 cycle baby though?He wants it as is, DuraForce and all. I don't know what to do at this point.
It is a 'one off, one of a kind original' and I'm thinkin' it's worth more than his offer.
I could use a new plasma tv.

[jr dragster Tyler]

You sure its not a scam there russ? That's an awfull lotta money for it.

[Russ2251]

No scam. I've known him several years.

[gocartkid]

Well if you do sell it then take careful measurements and lots of pics if you want to re-create it later.

[Russ2251]

take careful measurements and lots of pics if you want to re-create it later.Not a Problem. Next kart will be better. Maybe a Toro GTS mower engine (Suzuki) and yes it would be a 2 cycle converted vertical shaft.
A minibike may be on the menu as well.

[ironman]

after hours and hours of searching russ you are the only one that has a lawnboy setup nothing on the web ebay youtube or any other chat sight.if you can make that from one than we need to go in business

[ironman]

first picture as you can see no bolt holes for the exhaust
http://i206.photobucket.com/albums/bb106/jamieandterry/firstm.jpg
second picture this motor is from the utility lawn boy it has the bolt holes
http://i206.photobucket.com/albums/bb106/jamieandterry/secondm.jpg
motor mount plate doesn't look like it will be that bad on it.

[Russ2251]

the only one that has a lawnboy setup nothing on the webYou ain't seen nothin' yet. Soon I will post pics of Ryobi powered bicycle. Not fast but turns a lot of heads, even before I start it.

[ironman]

i hear you russ.but you got me interested in the lawn boy motors ok can you post up a picture of the carb setup you used .

[Russ2251]

second picture this motor is from the utility lawn boy it has the bolt holesThis might be the one to use. What is total length of shaft?

[ironman]

4 1/2 counting the threads and on the other motor that doesn't have the bolt holes it is 3 1/2 inches.by the way i got another great deal on a lawnboy its a delta force 4.25 or 4.75 have you seen one of them what do you know about them anything.- i can get it for 25.00 all together

[Russ2251]

can you post up a picture of the carb setup you used .Here you are. Please note that first pic shows a carb that I did not use. Last pic is different model engine but is basically the same arrangement.

[Russ2251]

great deal on a lawnboy its a delta force 4.25 or 4.75Never heard of this. Check names and model numbers. Always model numbers first.

[Russ2251]

4 1/2 counting the threadsThis is engine to use.

[JerryAssburger]

HOLY COW! Leave this thread for a few days, and look what happens!.....
Ironman has started his own Lawnboy Ranch, and Russ has started building customs for "Lawnboy County Choppers"!
...please don't forget about us little people!

Actually, I'm glad to see this trend. The 2 strokes are just too perfect for our craft to be ignored.

[kibble]

I know I keep saying this, but I really need to jump on getting that LawnBoy going! Maybe I'll get it out this weekend and do a little cleanup on it. I'll try to take pics of the dismantling process and what the parts look like. I need to get me in on some of this LawnBoy action!

Hmmm... I wonder what LawnBoy would look like if it was a cartoon character... :confused:

[Russ2251]

The 2 strokes are just too perfect for our craft to be ignored.Just what I've been trying to tell you guyz since I first logged in way back in November. Did anybody listen? Nooooo....and now Ironman and Russ2251 (aka Reed Valve Ranger) have sucked up the entire planets' inventory of Lawn-Boys. Now pay the price for your lack of vision (lightening bolts flying from tips of fingers). Consider yourselves vertically shafted. Take that my Otto Cycled friends!!!:devil2::roflol::sifone:
Hmmm... I wonder what LawnBoy would look like if it was a cartoon character... :confused:Or a PEZ dispens...uh, I mean box.

WHOA WHOA WHOA!!!! I never said anything bad about 2-cycles! I had one before I ever owned a 4 stroke. I loved the engine I just didn't have any of the tools of the knowledge at the time to do anything useful with it. It was a homelite weed whacker engine that I got for like $10. Second engine I ever played with, first was a 2 cycle R/C car nitro engine. Sometimes I would just start the 2 cycle homelite to listen to it run. I jumped right on the opportunity to buy that LawnBoy when I saw it. I've tried to look for more LawnBoys around here but I haven't found any.

Can I join your club now and not be vertically shafted?:Angel_anim:

[Russ2251]

I jumped right on the opportunity to buy that LawnBoy when I saw it.And there it sits...on garage floor in pieces. It's sacrilegious to the very core.
I would like to see pics of progress on a daily basis.:toetap05:
Can you meet the challenge?

[jr dragster Tyler]

I found a lawnboy 2 cycle mower in the garbage about a month ago and I opened up the plastic carb and there was like this foul smelling green "engine puke" in the carb bowl. I cleaned the carb as best as I could. Then it wouldntr start. Then I got P!@#$# at it and put ir back in the garbage:worried2: Dont hate me forever now russ.

[kibble]

And there it sits...on garge floor in pieces. It's sacrilegious to the very core.
I would like to see pics of progress on a daily basis.:toetap05:
Can you meet the challenge?

Whoa again! It's not sitting on the floor! There you go making assumptions! It's IN a box that's on the floor, mind you! Besides, I didn't just take it off the deck and not do anything else. I did order the Tillotson carbs. I still need to do something about the air filter though. I don't have a solution for that yet. I also went out and bought the fitting that will go to the pump in the carb.

I'm not trying to rush into it because it's the only engine of it's type I have. I want to take the time to get it done correctly. Who knows if I'll ever get the chance to get another one.

You should be yelling at Jr. here with his comment about throwing a lawnboy away! :roflol:

[Russ2251]

You should be yelling at Jr. here with his comment about throwing a lawnboy away!How can I yell at Jr?
Someday, perhaps soon, he will regret the error of his ways.
Maybe that's why his engine blew.
Destroying a Lawn-Boy has been known to bring on some really bad karma.:ack2::roflol:

[ironman]

me russ,kibble, we just need one more and we will be the elite lawn boy 4.:wai:

russ send me the part number on the carb. so i can check on ebay for on.didnt work on them none today went fishing been doing that alot here with the boys. and now im back out in the field no more office working for me. going to work on the motors this week.still got a few of the motors to take off and check them out.

[jr dragster Tyler]

No I threw out the lawnboy after the engine blow. But the lawnboy would run on starter fluid but not the carb. I think the plastic s@#$ carb is ruined. And plus the lawnmower didnt go to a landfill, some person picked it up off the curb in. It was gone in about 1 hour.

[Russ2251]

No I threw out the lawnboy after the engine blow.
Bad karma can work retroactively....or something.

[Russ2251]

send me the part number on the carbTillotson HL239B. I haven't seen them in awhile.

[Russ2251]

Will trade 196cc 6.5hp Honda GX-200 clone (Lifan) for Lawn-Boy DuraForce engine.

Lawn-Boy (engine only) can be any year DuraForce model 'E'. Must be a running engine but will consider non running if in good/excellent mechanical condition (unintended oxymoron).This offer is now officially closed.

[JerryAssburger]

Dang! The offer is closed!?! Too bad. I just found a project behind one of the machine shops in Chandler. Someone grafted two DuraForce motors side by side (twin with twin carbs) and converted it to horizontal. He sold it to me for $40 because it turns out it was too powerful and loud for his golf cart. I would much rather have a clone motor and....


...my nose is growing from this ridiculous lie! (Already big enough!)

[kibble]

Awwwww! I was gonna say! :roflol: :roflol: :roflol:

[carolinasled]

Hey guys, Been awhile since I last posted, I ran across this on a lawnboy search. I've got a 1996 Silver Series Lawnboy 4.75hp model 10227 serial 6947945. Just wondering is this engine Horizontible? If so Russ do you have a diy tech article?

[Russ2251]

Answered via PM.
Answers to most questions regarding vertical to horizontal conversions with most 2 cycle Lawn-Boy engines (not 'M's, 'C's or 'A's) are posted throughout this site (various threads).
Things are just too nuts for me to document all of it in one place. Perhaps a dedicated thread? Not up to me. May not be enough interest to keep it alive for very long.
On occasion, my inbox is inundated with questions. About half of them come from this site. I would rather answer questions in these forums so that anyone/everyone, who may be interested, can benefit.
Keep in mind that the use of L-B engines is not a cheap or easy answer to replace the garden variety Briggs or Tecumseh 4 cycle.
Thanx,
Rusty

[nickzom]

Do you still need The Duraforce?

I have a complete Silver Series mower, 6.5 Horse, Runs good.

I will part it out If I have to.

I will take the clone if you have it.

[Russ2251]

I, or somebody, will get back to you shortly.

[nickzom]

ok, i will be waiting.

[Russ2251]

Sorry for the delayed response.
I am no longer looking to trade my clone for a DuraForce as I won a 3rd one on Ebay.
Someone else in this forum showed some interest but decided against it. Hence the delayed response.
I would strongly recommend not parting out mower as they are much more valuable complete. I've seen them going for upwards of $300. Not many folks are interested in parts, unless it is a restoration project and parts cannot be gotten any other way. DuraForce are still relatively new (1998 to 2004) and new factory original parts are still in production.
Thanx for posting.
